best advice i was given was search...search...and search some more
you can go with a t3/t4 from turbonetics
i would say no more than 10psi, our motor can probably handle up to 14 but that pushin it. russianred just blew his ringlands @ 11 psi but he doesnt know if it was the tuners fault or just the motor.
look up russianreds thread, he was turboed for a long time on stock internals
also erik123456789 thread can help you as well. there are a lot of ppl that are on stock internals that are boosted. Aukmos & 1nonlyaccord are also boosted on stock
search a little bit and you will find some amazing info. i am currently doing a turbo build check it out
